The SpHb trend is dropping and the clinician may otherwise think haemoglobin is stable

Clinical Case

SpHb was retrospectively obtained for the surgical case shown below, in which clinicians could not assess the haemoglobin trend between invasive blood samples during the procedure1

SpHb Utility

Studies have shown that SpHb may help clinicians reduce blood transfusions in both low and high blood loss surgeries2,3

A randomised trial of 327 patients undergoing elective orthopaedic surgery, conducted at Massachusetts General Hospital (MGH), found that the use of continuous, noninvasive haemoglobin monitoring reduced the rate of transfusions when compared to standard care without continuous, noninvasive haemoglobin monitoring2

% of Patients Receiving RBC Transfusion2

A prospective cohort study of 106 neurosurgical patients found that adding SpHb monitoring to standard-of-care blood management resulted in decreased blood utilisation in high-blood-loss neurosurgery, while also facilitating earlier transfusions3*

Average Units Transfused Per Patient3

Clinical decisions regarding red blood cell transfusions should be based on the clinician’s judgment considering among other factors: patient condition, continuous SpHb monitoring, and laboratory diagnostic tests using blood samples.

* Study Protocol: The transfusion threshold of 10g/dL was predetermined by the study protocol and may not be appropriate for all patients. The blood sampling technique was the same for patients in both the control and the test group. Arterial blood was drawn from a 20 gauge radial artery cannula into 2mL ethylenediaminetetraacetic acid collection tubes, thoroughly mixed then sent immediately to the central lab for analysis by a haematology analyser. The reference laboratory device used for haemoglobin measurements in the study was a Coulter GEN-S Hematology Analyzer.
